What is the ruling for abandoning the stoning (Ramy) without an excuse?

Primary text

Abandoning the stoning incurs a sacrifice (dam). Ahmad preferred that if one abandons all days of stoning, a sacrifice is due. Abandoning a single Jamrah also requires a sacrifice, a position held by Ahmad, 'Ata, Al-Shafi'i, and the Ahl al-Ra'y (the Hanafi jurists). The evidence for this is the statement of Ibn Abbas: Whoever abandons any of his rites, a sacrifice is due upon him. Since abandoning part of the rites that does not invalidate the Hajj requires a sheep, similar to abandoning the overnight stay (Mabit). The prescribed time for the stoning ends at the conclusion of the days of Tashreeq (the three days following Eid al-Adha). If one departs before completing the stoning, the time is missed, and the required expiation for abandoning the stoning becomes obligatory.
